Absolute value of a number is the distance of a particular number considered from ‘0’ on the number line. Absolute value of a number, ‘x’ is represented as |x| where ‘| |’ sign is called ‘modulus sign’. Since distance can never be a negative value, hence absolute value can never be a negative number. Therefore, the final outcome of any absolute value function is positive, even though the number or the expression inside it can be either positive or negative. Absolute value calculator is a quick online tool which can easily calculate the absolute value of the given number or expression.

Example 1: If |2x – 3| = 5, then what is the value of ‘x’?

Since the expression, ‘2x– 3’ is under the modulus sign, we can split it in two ways.

(2x – 3)= 5 or - (2x – 3)= 5

Solve: 2x – 3 = 5, we get: 2x = 5 + 3==>2x = 8==>x = 4.

Check: |2*4– 3|= |5| = 5. Verified!

Similarly,-(2x – 3) = 5==> 2x– 3 = -5==>2x= -2 ==>x = -1.

Check: | (2*-1) – 3|= |-5| = 5. Verified!

Hence, x = 4 or x = -1

Example 2: If |3x + 3|= 6, then what is the value of ‘x’?

Since the expression, ‘3x + 3’ is under the modulus sign, we can split it in two ways.

(3x+ 3)= 6 or - (3x+ 3)=6

Solve: 3x + 3 = 6, we get: 3x = 6 - 3==>3x = 3==>x = 1

Check: |3*1+ 3|= |6| = 6. Verified!

Similarly, -(3x+ 3) = 6==>3x+ 3 = -6==>3x = -9 ==>x = -3

Check: | (3*-3) +3| = |-6| = 6. Verified!

Hence, x= -3 or x= 1

I have enjoyed my session with Aparna and it was helpful. I will hope to see her as my Math tutor in future sessions as well.

Your tutor has been such an inspiration to me as I have difficulty getting some of the physics concepts down and truly understanding them. She takes the time to fully explain each and every aspect of any problem I might ask for help and always with encouragement and humor.
